Denatured alcohol containing 1:4-dioxan



Patented Apr. 9, 1940 DENATUBED ALCOHOL CONTAINING 1:4-DIOXAN No Drawing. Application September 28, 1937, Serial No. 166,118

1 Claim.

This invention relates to the denaturing of ethyl alcohol, and to alcohol so denatured.

It an object of my invention to provide a denaturant which will render ethyl alcohol con- 5 taming it unfit for use as a beverage, which cannot be economically removed from the alcohol by any known methods, which will not render the alcohol unfit for industrial uses in which denatured alcohol has customarily been employed, l and which will be free from methanol. Other objects will hereinafter appear.

I have discovered that lz l-dioxan is an effective denaturant for alcohol. This compound has the structural formula:

In denaturing ethyl alcohol with my novel denaturant, I may use from 0.5 to parts of 1:4- dioxan, or even more, per 100 parts of 95% alcohol. lz l-dioxan may be used alone in denaturing, or it may be used in conjunction with denaturing materials derived from the destructive distillation of hardwood, such as those which are described in my U. S. Patents Nos. 1,975,090; 1,975,091 and 1,975,092. Likewise, it may be used in conjunction with amino compounds, or with any other denaturants with which it may be found to be compatible.

What I claim as my invention and desire to be secured by Letters Patent of the United States is:

Denatured ethyl alcohol containing, per 100 parts of 95% ethyl alcohol, from 0.5 to 5 parts, approximately, of 1:4-dioxan as an essential denaturing element.
